Laptop BIOS Master Password Generator

When you open a laptop & find yourself faced with the immediate black BIOS password screen & absolutely no idea of what password you used, all you gotta do is come to the Laptop BIOS Master Password Generator @

Many HP/Compaq, Dell, Lenovo, Sony, Samsung, Acer, Asus, Lenovo or Fujitsu laptop BIOS passwords can be revealed.

Hints & Tips


In the case of Asus laptops it’s the date code you require – enter an incorrect password then press Alt +R at the next prompt. Take that date & enter it in the BIOS Master Password Generator below in the same order (yyyy-dd-mm, mm-dd-yyyy or dd-mm-yyyy) as displayed on your Asus laptop.

NB: Use – as the date separator, not /.  This way dd-mm-yyyy, not dd/mm/yyyy. 


If your Lenovo laptop has an Insyde H20 BIOS, then your secret sauce is to use a USB keyboard to enter the master password generated here, then use a USB QWERTY keyboard to enter password.


For HP’s popular Elitebook & ProBook, there is an alternative method available here in the downloads section. Highly effective on vulnerable machines, full instructions included – please read them before you attempt BIOS password removal.


Press & hold the left Ctrl key when entering the password in Dell laptops, then hit Enter twice. Some Dell service tags are missing a suffix – first try the password generated, then try the passwords for all suffices by adding either -595B, -2A7B, -D35B, -1F66, -6FF1 or -BF97 to your service tag.

Many -6FF1 machines are cracking with our new -BF97 codes. Simply exchange the suffix on data entry then generate your code. (Don’t forget, left Ctrl then Enter + Enter)

Downgrading the BIOS can change your suffix, resulting in a successful password generation. If your BIOS is set to allow downgrades, this method will help.


For the later 6×4 password implementation, download & install Python 2.7 (available for all platforms), then grab the Fujitsu 6×4 Python script & save it in your Python directory. Double-click on the script, follow the simple instructions,  all done.
(Edit: I’ve now added the 6×4 script to the BIOS Master Password Generator)


Sony 4 x 4 Challenge Codes are a one-time password, generated fresh each boot. Do not turn the laptop off after obtaining the Challenge Code as the Master Password is specific to that code. Restarting before the password is entered will require a new Master Password.

We are blessed with the voluntary assistance of Mikrovr in the comments section of this page. Mikrovr is the creator of many of the Laptop BIOS Master Password Generators used on this page, & has built other generators that he keeps private but generously contributes solutions from. I stress that his attendance is entirely voluntary & is something that I personally am very thankful for.

Should the generators onsite here not provide the solution for your laptop, then join the conversation below. Ask the man himself, Mikrovr, to help you out. Make sure you leave full details – brand, model, response code to get the best possible chance of a solution.

Mikrovr’s solutions are the real thing. If he chooses to assist you to unlock your laptop, then you can say goodbye to the BIOS password. What else you can say is Thank You to him, seeing as he’s just turned useless junk into a laptop for you.

Anyway, whichever BIOS-locked laptop you have, grab the Machine ID Code – sometimes called the Service Tag, Challenge Code or Response Code  – usually displayed after submitting a few (3-5) incorrect codes – that’s the unique identifier we need. Pay special attention when reading the code, be careful not to confuse I & l or O & 0, B & 8, S & 5.

Now enter that code in the box below, hit the Crack It button…. Ka-ching!! No surveys to fill out, no pop-under pR0n adverts, just pure goodness & quite likely your Laptop BIOS Master Password too.

When you’ve done your Laptop BIOS Master Password Reset, please leave a comment, send a tweet, or do whatever peeps do on Facebook to tell the wwworld about your win…

    1. Hard drive passwords are a whole other thing. Luckily, replacement drives are at historical low prices, you can replace that existing locked HDD with a fresh new bigger, faster drive for not much $$.

      Replacing & fresh Winstall should take around an hour & the improvement will be noticeable.

    1. I’ve just updated the BIOS Master Password Generator. You should try Z7BFJhCcQ3t7a0iU or ymEyr72MJrMynG68. Either way be sure to hold left Ctrl down as you enter the characters, then hit Enter twice.

  1. Just to share the love, eventually got working on a Dell e5470 but for whatever reason I needed a separate USB keyboard. Do this and check and recheck your O versus your 0, your l versus your I etc. THIS DOES WORK.

    1. Yup, that’s what you gotta do on some (not all) Dell laptops. All visitors should read the provided information before using te generator, doing that seriously improves your chance of success.

  7. Hey Rene,
    Once you have the code, how do you input it? My laptop is locked after the three passwords so I need to re-boot to get to the password screen again but this seems to change the hash. Is there a way of inputting the password from the “System Disabled” screen?
